Export to Blender - Size problem

[Trenien]

Hi,

I've been trying to import my model into blender to try and render it with a bit more options than what the internal module allows, but I've stumbled on an unexpected problem: whatever I do, the imported object (the house, whether in obj or in stl) is too big and I can't work on it.

I've tried changing the units both in the scene and the display parameters, but it doesn't seem to work at all. What am I missing ?

Thanks

Ok, I've finally noticed that it's possible to set an import scale with an stl object. However, said import is monolithic, which isn't very useful.

Is there any way to do the same thing with an obj file ?

I think this is more ore less an help request...

I have limited experience only -

- I used Alias Mesh (*.obj) export and it preserve the objects in FC and import well to Blender (if it is 0.17_pre).
- I tried Wavefront OBJ - Arch Module. That has another pros, detecting coplanar surface, but as Yorik explained it is Python-based, it is comparatively slow and it take a loooooong time when I had a multi-storey building to export... and some other defect.

Hope it helps.

Thanks, I've always used wavefront.

I did find a a workaround:
- Export as obj (I used wavefront obj)
- Import it in blender
- Select all mesh objects, and export as obj from blender. The export dialog gives you the opportunity to scale the model (so 0.001).
- Import this new file in blender (where it will finally be the proper size).

Hi, doesn't it work to just scale it in blender, for example by typing 's0.001' with the meshs selected ?
